[6.16.z] Fix for teardown failures

[Satellite-QE]

Cherrypick of PR: #16211

Problem Statement

#15931 broke teardown of tests which use contenthosts registered through a Capsule because the registration target (where the host is registered to, Capsule in this case) was assigned to the host's self.satellite here, and in teardown we try to search and delete the host here, which fails since Capsule has no API

"error during teardown:\n'Capsule' object has no attribute 'api'"

Solution

As per @ogajduse++ proposal, provide the Satellite instance in host's self.satellite instead of the registration target (Capsule) so that it can be searched and destroyed at the Sat side.
